`kbd' was a (quite strange) macro in Emacs 23. It changed to a function
in Emacs 24. Your code works only in the last case. Call it a bug in
Emacs 23.
As long as you need to use both Emacs versions in parallel, you should
be safe when you use `read-kbd-macro' instead of `kbd'. It does the
same, but should work in both versions.
Regards,
Michael.
